My invention relates to improvements in dis tributor nozzles. i I The invention is particularly adapted for the distribution of spray over a wide area under low 5 head or pressure.

An object of my invention is to provide a spray nozzle which. will give an even and complete spread of spray over a surface of large diameter under low head or low pressure; a further object of my invention is to provide means for breaking up a stream of water underlow pressure and distributing the water inthe form of finely divided spray over a wide area. 7

'l further object of my invention is to provide a non-clogging spray distributing means;

i accomplish these and other objects by my invention, a preferred embodiment of which is illustrated in which,

Figure l is a side elevation of my improved distributor nozzle.

Figure 2 is a section of the same on; the line 2-2 in Figure l and Figure 3 is a perspective view of the upper disc.

Similar characters of reference refer to similar parts throughout the several views.

My improved device comprises askeleton frame Bil posed raised section B with a flaring periphery 40 0 having convex sides, the upper surface 5 .of

the said raised section 5 being bevelled. Y

The. concave sides I of the raised section 5 merge into the flat marginal horizontal surface 9 of the upper face'of the disc 2 which has a 4 sharp peripheral margin II. It is important I that the marginal upper surface 0 of I be flat and horizontal and I produce the sharp edge I. by so shaping the under side only of the peripheral margin H of the dis'c 2 as to produce W the desired sharpedge.

The upper disc 2 may be castintegral with the frame I as shownln the drawing but it is obvious that the disclmay be supported in any other desired manner without departing from my Y invention.

the accompanying drawing, in tram the supply pipe it at low pressure.

orifice ii of thedisc 2 being smaller in diameter so than the discharge port i, the outer marginal (bi, ass-r21) The disc t positioned axially below and spaced from the upper disc ,3 is preferably supported by integral brackets it on the frame l and is of like construction to that of the disc 2. it is,

however, smaller than the disc 2 and its central ,5

aperture i3 is axially disposed with reference to the aperture ii in the disc 2.

Below and spaced from the'disc ii, I preferably provide a third disc Q having a slightly rounded upper face M and which may have a lo small central perforation l5 axially disposed with reference to the central aperture it in the disc ii.

I provide in the upper part of the frame 0 a head it having a threaded mouth or admission port ll adapted to receive the water supply in pipe it. t

The device being thus assembled, the water to be cooled or aerated is delivered to the nozzle The portion of the entering stream will strike the bevelled edge 5 of raised portion 5 and the upper surface of the disc 2 and will be thrown out or splashed laterally to a considerable distance in 25 the form of a circular sheet of finely divided spray and the sharp'edge of the disc 2 will minimize. the capillary attraction between the disc and water whereby little, if any, water will cling to or'fall perpendicularly from the edge'of the disc.

- The operation above described will ensue at the disc 3 with reference to ,the water passing through the aperturefi in the disc 2 and there will be produced by these two discs two evenly spaced dome shaped spray clouds one within the 85 other. i

I have discovered that comparatively slight changes and modifications in the form of the discs and particularly of their upper surfaces produce marked changes and variations of the resuiting spray cloud.

It is obvious that additional discs of like construction may be employed if desired. I have, however, found in actual practice that two of these discs are sufficient in ordinary work.

The water which passes through the aperture IS in the disc I will fall upon the disc 4, being the last disc of the series. In this final spray disc 4, I prefer to omit the central pyramidal raised section and to slightly round or curve the final disc I will be splashed off in a still smaller spray 'dome' inthe manner above described, a

I substance, such as sand, tar, leaves or other sususe of my improved nozzle, that, by reason of the small quantity passing through the central perforation l5.-

It will thus be found in operation that the water delivered to the device even at a low head and pressure will be completely converted into a pended matter, nozzles of the old type frequently clog or become obstructed and in gasoline distilling plants and the like, where there is a tarry substance carried by the water, it has been found that, in distributor nozzles'of the present typ deposits accumulate on the discs to such an extent that the efliciency of the device is seriously interfered with. I have found} in practical shape and form of the discs, there is no accumulation of foreign matter on the discs and that all foreign matter is washed off of the discs by the flowing water so that the discs are kept clean and free from accumulated deposits and the nozzle does not. clog even under the most adverse conditions but operates eficiently in throwing a film of water over cooling coils and the like.

Having thus described my invention, what I claim is: K 1. In a device of the character described, means for spraying water comprising a source of supply having a delivery ort'and a platelposi tioned below and spaced from said port, saidplate having on its upper face a centrallyapertured raised section with .flaring sides, a' list horizontal annular surface, surrounding said raised section andhaving a sharp marginal edge;

' 2. In a device, of the character described, means for spraying =water comprising a source of supply having a' deliveryport and a plurality of horizontal graduated spaced plates below'the said delivery ,port each having on its 'upperface a the upper face of said disc, and a flat horizontal a plurality of centrally apertured graduated discs I ALEXANDER 1301mm
